Using the Yellow Card scheme
Can I report side effects officially?
In the UK, both patients and healthcare professionals can report side effects directly to the Medicines and Healthcare products Regulatory Agency (MHRA).
This is through the Yellow Card scheme.
This contributes to an important safety database, especially for new and unexpected side effects.
Side effects from new drugs often emerge after approval. It is worth reporting something you are worried about even if you aren’t sure if this is a side effect.
Side effects can be reported online with this scheme and through the Yellow Card app.
